Detailed Description

Display conduits provide support for adding custom display functionality during drawing inside of a display pipeline/viewport.

A subclass of a conduit specifies what channels or "phases" of drawing that it wants to be involved in.

Conduits may be "bound" to specific display pipelines or viewports which means that they will only operate with the objects they are bound to. If a binding is not defined, the conduit will operate in all display pipelines.

Constructor & Destructor Documentation

CRhinoDisplayConduit() [1/2]

CRhinoDisplayConduit::CRhinoDisplayConduit	(	CSupportChannels	channel_mask,
		bool	enable
	)

Parameters: channel_mask: [in] Set of CSupportChannels that this conduit is interested in. enable: [in] Should the conduit initially be enabled? Remarks: Do not use SC_POSTPROCESSFRAMEBUFFER unless you absolutely need to. The display pipeline will check to see if it has any conduits that require this phase of drawing and will only perform a postprocess if one exists. Post processing of the frame buffer requires multiple dib copies at the end of drawing a frame and will cause a constant performance hit on display speed.

Since most of the time a conduit needs to only implement 1 to 2 channels at at time, it is also recommended that you do NOT use SC_ALL_CHANNELS to construct your conduit...This will make your counduit (and the pipeline) very inefficient. Example: If you had a conduit subclass that wanted to pay attention to object drawing and foreground drawing, you would set up the constructor as follows

CMyDisplayConduit::CMyDisplayConduit() : CRhinoDisplayConduit( CSupportChannels::SC_DRAWOBJECT | CSupportChannels::SC_DRAWFOREGROUND ) { ...set up some other class variables } ON_DEPRECATED - removing deprecation for the time being so we can find and clean up other outstanding warnings

)

const

Attributes...

Parameters: channel: [in] CSupportChannel or a list of CSupportChannels that are or'd together Returns: True if this conduit supports given channel or list of channels. The supported channels are the ones that were defined in the conduit's constructor

ConstantBinding()

bool CRhinoDisplayConduit::ConstantBinding

(

)

const

Description:

Disable()

void CRhinoDisplayConduit::Disable

(

)

Description: Turn this conduit off. When a conduit is disabled, it will not participate in any custom drawing activity.

Returns: The document that the conduit is working with at the time of ExecConduit. Remarks: The returned pointer may be null.

Enable() [1/2]

void CRhinoDisplayConduit::Enable

(

)

Description: Turn this conduit on. When a conduit is enabled, it's ExecConduit function is called for each viewport that this conduit pays attention to. ON_DEPRECATED - removing deprecation for the time being so we can find and clean up other outstanding warnings

Enable() [2/2]

void CRhinoDisplayConduit::Enable

(

unsigned int

docSerialNumber

)

EnableConstantBinding()

void CRhinoDisplayConduit::EnableConstantBinding

(

bool

enable = true

)

Description: When a conduit runs inside of a pipeline, it is said to be "bound" to that pipeline. By default all conduits are bound to all existing pipelines and any newly created ones...This is known as "constant binding"...If a conduit is only supposed to run/execute inside a specific pipeline/viewport (or set of viewports) then constant binding must be disabled, and the conduit must then be manually "bound" to a specific pipeline/viewport. See comments on all of "Bind()" methods.

Note: You can still bind conduits to specific pipelines/viewports, but the conduit will have to manually check for bindings inside of "ExecConduit()" using the "IsBound()" methods. By disabling constant binding and manually binding your conduit, will force your conduit to only run in specific pipelines/viewports (ie. no checks are necessary, they're handled by the pipeline).

Parameters: enable: [in] Set to false to disable constant binding, true to enable it.

ExecConduit()

virtual bool CRhinoDisplayConduit::ExecConduit ( CRhinoDisplayPipeline &  pipeline, UINT  channel, bool &  terminate  )

pure virtual

Operations...

Description: Conduits should/could be thought of as small pieces of code that get "executed" inside of Rhino's pipeline...and by specifying which "channel" your conduit executes in, allows you to determine where and when your code runs.

This function is called for every CSupportChannel that this conduit has been constructed with during the process of drawing a single frame. ExecConduit is not called when the conduit is disabled.

Parameters: pipeline: [in] the pipeline that is currently executing and calling this conduit. This is the pipeline you should be calling "Draw" functions on if you want to perform any custom drawing. channel: [in] This function can be called multiple times by a pipeline while drawing a single frame. The channel parameter specifies what part of CSupportChannels is currently being executed terminate: [out] Set this to true if you don't want other conduits to perform operations in the current channel after this function returns. Typically you will leave this parameter alone and allow other enabled conduits to perform their custom drawing code. Returns: True if the function completed successfully. If this function returns false, something bad occurred and drawing of the current frame stops.

Implemented in CRhinoGumballDisplayConduit.

FromRuntimeSerialNumber()

static CRhinoDisplayConduit* CRhinoDisplayConduit::FromRuntimeSerialNumber ( unsigned int  display_conduit_sn )

static

Parameters: display_conduit_sn - [in] Returns: If display_conduit_sn identifies an existing CRhinoDisplayConduit, then a pointer to that conduit is returned. Otherwise, null is returned.

GetGeometryFilter()

unsigned int CRhinoDisplayConduit::GetGeometryFilter

(

)

const

Description: Returns the current geometry filter set for this conduit. Possible values will be based on ON::object_type enum and the different combinations that can exist through or-ing ( | ) them together.

Note: If you passed 0 to SetGeometryFilter(), then this routine will return ON::any_object and not 0.

GetObjectFilter()

ON_UuidList CRhinoDisplayConduit::GetObjectFilter

(

)

const

GetSelectedFilter()

void CRhinoDisplayConduit::GetSelectedFilter	(	bool &	on,
		bool &	checkSubObjects
	)		const

Description: Get filter settings for selected objects. See SetSelectedFilter comments. Parameters: on - [out] true limits the conduit to selected objects checkSubObjects - [out] if true and on=true, then the conduit will be called for objects that have some subset of the object selected, like some edges of a surface.

InterestedInObject()

bool CRhinoDisplayConduit::InterestedInObject

(

const CRhinoObject *

)

const

Description: Determines if the passed in object's "type" matches the currently set geometry filter. This is more or less a helper function used when processing object-based channels.

Returns: true - if passed in object's type matches against the current geometry filter. false - if passed in object's type does NOT match against the currently geometry filter.

Note: If the current geometry filter is set to ON::any_object OR 0, this routine will always return true, and no conditions or comparisons are checked or made.

IsBound() [1/4]

bool CRhinoDisplayConduit::IsBound	(	const CRhinoDisplayPipeline &	pipeline,
		bool	ignore_state = false
	)		const

Description: Determines if this conduit is bound to a specific pipeline or viewport Parameters: pipeline: [in] the pipeline to check binding against ignore_state: [in] determines if whether or not the "constant binding" state should be ignored. (See comments for "EnableConstantBinding()"). In other words, if this conduit is using constant binding (default), then it doesn't really matter if it is bound to anything since constant binding means "always bind to everything". However, most of the time it is necessary to pay attention to the state since conduits can be manually bound and programs need to know which pipelines this conduit is bound to. There are certain conditions where the display pipeline need not pay attention to the constant binding state, but most likely all other programs do...It is recommended that if you do not understand exactly what is going on here, that you just use the default.

RuntimeSerialNumber()

static unsigned int CRhinoDisplayConduit::RuntimeSerialNumber ( const CRhinoDisplayConduit *  conduit )

static

Description: Get the uniuqe runtime serial number for a given display conduit

SetGeometryFilter()

void CRhinoDisplayConduit::SetGeometryFilter

(

unsigned int

geometry_filter

)

Description: The geometry type filter controls which types of geometry (points, curves, surfaces, meshes, etc.) will be processed in any "object based" channels (see SC_OBJECT_BASED_CHANNEL)

Parameters: geometry_filter - [in] an unsigned int made by or-ing ( | ) values from the ON::object_type enum. However, If you pass 0, then this is interpreted as "no geometry filter", which means ALL geometry will be processed and is equivalent to passing the value ON::any_object.

Note: The default geometry filter for all conduits is ON::any_object. If you want your conduit to only process specific types of objects, then you must set the geometry filter for your conduit accordingly. Using ON::object_type might seem like overkill for this purpose (since not all types are technically "drawn" as objects within the channels), however, this is more consistent with how filtering works in other classes.

For example: If you have a conduit that executes in the SC_DRAWOBJECT channel, but you're only interested in processing "Light" objects, then you would set your conduit's geometry filter like so:

myConduit.SetGeometryFilter( ON::light_type );

...a good place to set this would be either in your conduit's constructor or just before you enable your conduit, depending on how you've decided to use this feature.

m_Channels

const CSupportChannels CRhinoDisplayConduit::m_Channels

protected

The channels that this class was constructed with.

m_pChannelAttrs

class CChannelAttributes* CRhinoDisplayConduit::m_pChannelAttrs = nullptr

protected

Channel attributes are set up for each channel or "phase" of drawing. If the conduit modifies these attributes inside of the ExecConduit function, the display for the current channel will be changed based on these attributes. Note: See the definition of CChannelAttributes for a "logical grouping" of which attributes apply to which channels. Note2: Changing channel attributes that are not part of the "current channel" context will have unknown and unexpected results.

m_pDisplayAttrs

CDisplayPipelineAttributes* CRhinoDisplayConduit::m_pDisplayAttrs = nullptr

protected

Global pipeline display attributes that the conduit can adjust to modify the display Note: Changing display attributes may have no effect based on which channel this conduit is currently running in (ie. The pipeline may step on any changes). A good rule is to only change these attributes inside SC_OBJECTDISPLAYATTRS, or all OBJECT DRAW channels, anywhere else may produce unexpected results.

m_rhino_doc_sn

m_rhino_view_sn

unsigned int CRhinoDisplayConduit::m_rhino_view_sn = 0
